4 Claims. (Cl. 20-4) 1 This invention relates to a novel combination covering and insulating imit for roofs and walls adapted to be applied over existing shingles or siding as an under cover for a composition shingle or siding to be applied thereover.

In applyingA composition shingles or siding of either asphalt or asbestos or the like to existing roofs or wooden walls or to new structures, it is a practice to initially cover the roof or siding with heavy felt paper and where the shingle roof or siding is stepped to rst apply strips of substantially wedge shaped cross section in the recesses of the roof or siding to provide a substantially smooth and nat surface over which the felt paper is applied. These beveled iiller strips which are formed of wood must be nailed in place after which the felt paper must either be nailed to the roof or siding with large headed nails or held by retaining strips which are nailed to the roof or siding. The wood filler strips aiord a space which is readily accessible to termites and if any seepage of water occurs to dampen such strips it is quite common for the strips to buckle and injure or displace the composition shingles or siding which is applied thereover. Furthermore, the felt paper is heavy and difficult to' handle and if a rain occurs before the composition shingles or siding can be applied thereover. it is ordinarily necessary to replace the paper.

Accordingly. it is a primary object of the present invention to provide a covering to be applied beneath composition shingles or siding which will eliminate the use of the beveled iiller strips and felt paper and which will additionally insulate and fur the roof or wail and which is not accomplished by the felt paper and beveled filler strips.

Still another aim of the invention is to provide a combination insulating covering unit for roofs and walls capable of being very conveniently handled and quickly and easily applied to a roof or wall and which is capable of withstanding without damage a heavy rain before composition shingles or siding are applied thereover.

Various other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawing, illustrating a presently preferred embodiment thereof, and wherein:

Figure 1 is a fragmentary end elevational view, partly broken away and partly in section illustrating the invention applied to a roof and wall of a building;

Figure 2 is a vertical sectional view takenl substantially along a plane as indicated by the line 2 2 of Figure 1;

Figure 3 is an enlarged vertical sectional view taken substantially along a plane as indicated by the line 34 of Figure 1;

Figure 4 is an enlarged fragmentary perspective view showing several of the roof or wall cov- 2 ering units as they would appear when assembled together in a course;

Figure 5 is a plan view, partly in section looking toward the inner side of one of the covering units and on a reduced scale, and A A Figure 6 is a perspective .view looking toward the inner side of said covering unit and with the insulating filler thereof removed.

Referring more specifically to the drawing, the novel roof or wall covering unit in its entirety and which comprises the invention is illustrated in Figure 5 and designated generally 'I and includes a piece of heavy felt paper, designated generally!! of the type usually employed for covering a roof or wall beneath the composition shingle or siding and which includes an elongated strip designated generally 9 and an extension I9 which forms a lateral extension of the upper edge I l of the strip 9. As clearly illustrated in Figures 5 and 6, the extension I0 trminates short of the ends of the strip 9 and is adapted to be folded over and overlie a portion of one side of the strip 9. as illustrated in Figure 6.

The extension I9 is secured to the said side of the strip 9 by a ller I2 of insulating material which may be formed of sawdust, rock wool or wood ber which is bonded together by a. suitable binder such as asphalt and which is molded so as to be substantially wedge shaped in cross section, as best illustrated in Figures 3 and 4. The widest longitudinal edge of the insulating filler I2 is disposed adiacent the uppel edge II of the strip S so that the extension I0 extends outwardly from said edge I I at substantially a right angle to the strip 9 and then extends downwardly and in converging relationship to the strip 9. As previously stated. the ends of the extension I0 are spaced from the ends of the strip 9 so that the end portions of said strip 9 form end flaps I3 and the free edge of the extension I0 is spaced from the bottom edge of the strip 3 so that the portion of the strip 9, located below the extension I0 and filler I2 forms a bottom nap Il. i A

The roof and wall covering and insulating unit 'l may be made in various lengths and widths to be conveniently handled and packed in bundles and are adapted to be used primarily in applying composition roofing shingles over an existing shingle roof or in connection with applying composition sding over an existing stepped siding of a building, as illustrated in Figures 1, 2 and 3 and wherein a portion of such a side wall I5 and such a roof I6 of a wooden building, designated generally II is illustrated. The application of the 55 covering and insmatmg una 1 to the wan and roof are exactly the same and accordingly will only be described in connection with the wall I5. Musa-ated in Figmesz and 3, the siding members IB of the wall I5 are ordinarily formed of wood and are stepped so that each of the siding members I8 is substantially wedge shaped in cross section and with its bottom edge constituting its widest edge and its upper edge constituting its narrowest edge. The covering and insulating unit 1 are applied in courses starting at the bottom and working toward the top of either a wall or roof and the illier portion I2 of each unit I is of substantially the same width as the exposed surface of one of the siding members I8 or one of the roof shingles. In the bottommost course of unit 1, the bottom flaps Il may be cut oil' or folded under and the end aps I3 adjacent each end of the wall and of all the courses of the units 'I may likewise be cut oi or folded under. Each unit 1 may be secured to the wall or roof by approximately three spaced driven fastenings IS which are driven through the pad or filler I2 near its wider, upper edge. best illustrated in Figure 3, with the sides of the strips 9 on which the fillers I2 are disposed positioned innermost or against the siding members I 8 and the adjacent units 1 of cach course are disposed with the ends of the pads in substantially abutting engagement, as best illustrated in Figure 4. This is accomplished by folding one end iiap I3 across the end of the filler or pad I2 of its unit 1 and then extending it so that it will lie beneath the adjacent end of the adjacent pad or illler I2 while the other adjacently disposed end flap I3 is extended to overlie the outer side of the strip 9 of the adjacent unit 1, all as clearly illustrated in Figure 4. The successive courses may be disposed in staggered relationship, as illustrated in Figure 1 and as seen in Figure 3, the widest portion of each pad or ller I2 is of a sulcient width preferably to extend slightly outwardly from the widest part of the siding member I8 disposed thereabove and so that the narrow bottom edge of the iiller I2 of the unit 1 disposed thereabove may abut thereagainst. In each of the courses of units 1, above the lowermost course, the bottom flaps I4 will extend downwardly to overlie the upper portion of the units 1 of the course disposed directly therebeneath and so as to cover the driven fastenings I9 by which said lower course is secured to the wall I5 or roof I6.

Accordingly, it will be readily apparent that the entire wall or roof surface is covered by the llers I2 of insulating material and by two plies of the felt paper 8, as illustrated in Figure 3, so that the wall I5 or roof I6 will be insulated against heat or cold and will be adequately Protected by the two spaced felt paper coverings 9 and III. After the wall I5 or roof I6 has thus been covered completely with the courses of the units 1 the siding members 20 or shingles 2I are applied thereover and secured in any conventional manner by driven fastenings 22, which may be arranged, if desired, so that the fastenings will be covered by the overlaps of the siding members or shingles. It will be noted that the pads or llers I2 will also space the shingles 2| or siding members from the roof I6 or wall I5, respectively, to thereby function additionally as furring members.

Various modifications and changes are contemplated and may obviously be resorted to, Without departing from the spirit or scope of the invention as hereinafter dened by the appended claims.
